CONVEYING MECHANISM FOR COKE-DRAWING MACHINES,

SPECIFICATION formingpart of Letters Patent N 0. 728,168, dated May 12,1903.

Application filed August 14, 1902- Serial No. 119,620. (No model.)

To alt whom it may concern:

Be it known that 1, JOHN A. HEBB, a citizen of the United States,residing at Uniontown, in the county of Fayette and State ofPennsylvania, have invented certain new and useful Improvements inConveying Mechanism for Coke-Drawin g Machines, of which the followingis a specification, reference being had therein to the accompanyingdrawings, forming part of this specification, in which- Figure 1 is aplan view of my improved coke drawing and conveying machine, showing itin position in front of an open door,- portions of thetraveling'conveyer and-"thebeam being broken away. Fig. 2 is a detailcross-sectional view on the line II II of Fig.1. Fig. 3 is a view inside elevation of the apparatus. Fig. 4 is a longitudinal verticalsection through the delivery-conveyer, indicated by the line IV IV ofFig. 1. Fig. 5 is a simi lar view indicated by the line V V of Fig. 1,showing the receiving-conveyor in elevation. Fig. 6 is a plan viewshowing the driving means for both conveyors.

My invention relates to apparatus for drawing coke from the oven and forconveying it away therefrom for delivery into cars for transportation orupon the yard.

The apparatus consists generally of a moving structure adapted to travelforward and back in front of the ovens, provided with a turn-tablecarrying a reciprocating beam adapted to be extended into and withdrawnfrom the oven to empty the contents therefrom.

The present application refers more particularly to the conveyingmechanism which receives the coke fromthe oven-door and conveys it awaytherefrom at whatever position the machine may assume and finallydelivers it as indicated.

Referring now to the drawings, A represents the framework of a portablecarriage carrying a turn-table B,upon which are mounted the variousmanipulative portions of the machine.

Mounted in suitable bearings is a main shaft 4, driven at one end by asuitable prime 6, which bevel-wheelin turn meshes into the :bevel-wheel11 on shaft'fi, so that when main "shaft 4 is driven'shaft 5 will alsobe continuously driven in the direction indicated by the arrows. Fromthese main shafts all of thevarious operations ofthe machine aretransmitted, the conveyors being driven. bysprocketwheels mounted on theends of shafts 4and '5, respectively, as shall be hereinafter de- :1 I27 is the reciprocating beam, adapted to be extended into and withdrawnfrom the oven and provided at its forward end with a rakehead'3l,'adapted to engage a portion of the coke in the oven and to draw itout through the door and to discharge -it-upon the receiving-conveyer,the beam being manipulated.

by suitable gearing fully described and shown in other contemporaneouslyfiled applications bearing the serial numbers 119,617, 119,618,and,119,6l9. i

' At'the side of the machine adjacent'to the oven is located theconveyer0, consisting of a series of slats 81, forming an end less apron,secured upon and carried by sprocket-chains 84: The chains are carriedupon sprocketwheels 82 and 83, mounted on the head-shaft -85-andtail-shaft 86, respectively, carried-in bearings onlongitudinalme'mbers87 or other suitable framework rigidly supportedvfrom framework A. The head-shaft 85 is driven through sprocket-wheel 88on shaft 5 and chain 89, passing around driven sprocketwheel 90, bywhich 'continuousmovement' is imparted to the conveyer during therotation of the counter-shaft 5. 4

Arranged at right angles along one end of the apparatus is the conveyorD, which is of any suitable length adapted to the width of the yard orthe distance to which it is desired to convey the coke, and thisconveyor is generally similar to the one just described, the

slats, however, being somewhat separated to permit of the escape of thedust or small particles of coke. The slats 81 are mounted uponsprocket-chains Sat, passing around sprocketwheels carried by head-shaft91 and tail-shaft 92, the head-shaft being mounted in bearings rigidlysupported from the framework of the machine.

The tail-shaft 92 is mounted in hearings in the outer end of thesupporting-framework 97, which may be rigidly carried upon suitablesupporting mechanism extending outwardly from the machine, which ispreferably pivoted to said supporting-framework at 98 adjacent to thehead-shaft, thereby permitting the inclination of the conveyer to bevaried as desired. The pivotal bearing 98 is adjacent to the drivingsprocket-wheel 94, so that variations in the height of the conveyer willnot affect the tension of the drivingsprocket-chain. The conveyer-D isdriven by sprocket-wheel 94 on shaft t and chain 95, passing around adriven sprocket-wheel 96, mounted on tail-shaft 92, the speed of theconveyer, as is also the case with the conveyer 0, being regulated bythe relative proportions of the driving and driven sprocketwheels.

For the purpose of preventing clogging of the apparatus the speed ofconveyer D is somewhat greater than that of conveyer 0, so that the cokedischarged on conveyer D will always be carried away somewhat fasterthan it is received.

Conveyer D is supported at its outer end or at any intervening positionby any suitable framework, either extending outwardly from the mainframe or downwardly to the ground from the conveyer in the manner of aprop; but as various means may be utilized for thispurpose,thesupportingdevices are not necessarily specifically shown ordescribed.

As shown by the drawings, the general level of the first conveyer C isbut slightly below the level of the oven-floor, but is considerablyhigher than the inner end of the conveyer D, and the coke from conveyerO is discharged upon an inclined apron or floor 99, extending downwardlyfrom its delivery end to the inner end of the conveyer D, while on thefront and also the back of conveyer O are sloping pans or floors 100, ofsheet metal, adapted to receive the overflow and to return it to theconveyer. These pans connect with a surrounding hopper 101, havingsloping sides adapted to deliver coke from all directions upon thetraveling slats, and for the full length of the conveyor D it isprovided with a pan 102, having upwardly-extending sides 103, upon whichpan and between which sides travels the sprocket-chain and slats of theconveyer.

For the purpose of providing a quiet hearing for the slats the floor ofsaid pan may be provided with longitudinal strips of wood 104,

upon which the chains or slats are adapted to travel.

At any position in the length of conveyer D, but preferably near thefront end, one or more openings are made in the floor, and below suchopenings is located the laterally-inclined dust-chute 105, adapted toreceive the dust,which will fall through the slats and be drawn forwardto such position at which it will fall by gravity and will discharge ateither side of the conveyer.

As will be understood, both conveyers 0perate continuously during theoperation of the machine, and the handling of the coke is doneautomatically from the time it is drawn to them from the oven.
